关于php写数据库乱码问题

Jun 23, 2016 pm 01:36 PM

在php页面内插入数据到数据库后,数据库内显示乱码。
数据库字符集:


页面字符集:


在插入前执行mysql_query("set names 'utf8'")能解决问题
网上说set names 'utf8'就是将character_set_connection,character_set_result,character_set_client设置成utf8,
但是我已经将数据库的所有字符集都设置成了utf8,却还是会乱码
另外,在前端插入中文乱码,在后台直接插入中文不会乱码。
想知道哪里还有问题,求各位大神解答

只要你的数据库安装时没有选择 utf8 
那么 mysql_query("set names 'utf8'") 总是必要的

那mysql_query("set names 'utf8'")不是就设置了那几个变量吗?
还是说还做了其他的事情?

如果你的 MySQL 是带 my.ini 启动的,那么只需修改 my.ini 中的
default-character-set=latin1
条目

我的是my.cnf,我已经在里面将默认值都设置成utf8了啊

我并没有说一定可以
因为安装时默认是 latin1 不容易改的

那么 mysql_query("set names 'utf8'") 总是必要的

因为即使你改了,旧数据还是会有问题的。

那如新建一个库呢?可以解决不?

恩,谢谢各位,刚刚实验了一下,确实可以。
网上文章都没说明对已存在的库不起作用

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
